DICE: all future Battlefield 4 content will be free

DICE is working on a lot of extra content for Battlefield 4. We’re getting night maps, a brand new community map, and some unannounced content as well.

But Battlefield 4 players have been asking whether all this new content will be free, and DICE has now confirmed that, yes, all future BF4 content will be free of charge for all players.
DICE’s David Sirland confirmed that all future content will be free for everyone, that includes both Premium and non-Premium players. The new content includes both the new maps, and the upcoming Gunmaster game mode and new weapons.
The upcoming Spring patch will include the Gunmaster game mode and 5 new weapons, including the AN-94 assault rifle. All of these will be free for everyone.
In the future, the Night Maps update will include night versions of several maps, including Siege of Shanghai, Zavod 311, and Golmud Railway. You can check out some Battlefield 4 night maps screenshots here.
Finally, this Summer, DICE will release the brand new community map, which recently entered production. In addition to the community map, an unannounced map remake from a former Battlefield game is also in the works and will be released in the future.
Overall, Battlefield 4 players have a lot to look forward to in the upcoming months.
